Video motion analysis is a technique used to get information about moving objects from video. Examples of this include gait analysis, [1] sport replays, speed and acceleration calculations and, in the case of team or individual sports, task performance analysis. The motion analysis technique usually involves a high-speed camera and a computer ...
A typical gait analysis laboratory has several cameras (video or infrared) placed around a walkway or a treadmill, which are linked to a computer. The patient has markers located at various points of reference of the body (e.g., iliac spines of the pelvis, ankle malleolus, and the condyles of the knee), or groups of markers applied to half of ...
Prior to the introduction of the C3D file format almost all biomechanics and gait analysis software was written for each specific 3D system manufacturers file format. As a result, researchers and clinicians were restricted to either writing their own analysis software or else using only the software provided by with their 3D data collection system.
Motion analysis is used in computer vision, image processing, high-speed photography and machine vision that studies methods and applications in which two or more consecutive images from an image sequences, e.g., produced by a video camera or high-speed camera, are processed to produce information based on the apparent motion in the images.
X-ray motion analysis is a technique used to track the movement of objects using X-rays.This is done by placing the subject to be imaged in the center of the X-ray beam and recording the motion using an image intensifier and a high-speed camera, allowing for high quality videos sampled many times per second.
Gait Abnormality Rating Scale (GARS) [1] is a videotape-based analysis of 16 facets of human gait. It has been evaluated as a screening tool to identify patients at risk for injury from falls. [2] and has been used in remote gait evaluation. [3] A modified version was published in 1996. [4]
